Q

What are the four Principles of preventing infection during an injection? What techniques should be used for each?

A
  1. Prevent contamination of solution (ampules closed, med removed quick)
  2. Prevent needle contamination (avoid touching contam. surface; avoid touching length of plunger, keep tip covered)
  3. Prepare skin (wash soiled with soap/water, friction and circular motion with antiseptic swap, swab from center of site and move outward in a 5-cm (2-inch) radius
  4. Reduce transfer of microorganisms (perform hand hygiene for a minimum of 15 seconds)

A

6 mm (1/4 inch) -light coloured

62
Q

What are some contraindications your should assess for prior to administering an ID injection?

A
  • reduced local tissue perfusion
  • history of serious adverse reactions or necrosis that happened after previous ID injections
63
Q

Why should an ID injection site be free of discoloration or hair?

A

So you can see results of skin test and interpret them correctly

64
Q

When using forearm for ID injection, how should you landmark the best place? Where should you use if you can’t use forearm? If this site isn’t good, what other places would be appropriate?

A

Select site three to four finger widths below anticubital space and one hand width above wrist

If you can’t, inspect upper back

If necessary, use sites appropriate for SUBQ

65
Q

What are the steps from start to finish when administering an ID injection?

A
  1. Clean site
  2. Hold swab or gauze between third and fourth fingers of nondominant hand
  3. remove needle cap from needle by pulling straight off
  4. hold syringe between thumb and forefinger of dominant hand with bevel of needle pointing up
  5. Administer injection
  6. Help pt to comfortable position
  7. Dispose
  8. Remove gloves and perform hand hygiene
  9. Stay with patient for several minutes and observe any allergic reactions
66
Q

Why do you stay with the patient for several minutes after an ID injection?

A

To observe for any allergic reaction: dyspnea, wheezing, and circulatory collapse = SEVERE anaphylactic reaction

67
Q

What are the five steps of administering injection

A
  1. with non dominant hand stretch skin over site with forefinger or thumb
  2. with needle almost against pt skin, insert it slowly at 5 to 15 degree angle until resistance is felt; advance needle through epidermis to approx. 3 mm (1/8 inch) below skin surface. You will se bulge of needle tip through skin
  3. inject med slowly. Normally you feel resistance. If not, needle is too deep; remove and start again
  4. When injecting, note that small bleb 6mm[1/4] inch resembling mosquito bite appear on skin
  5. withdraw needle and apply gauze or alcohol swab gently over site (DO NOT MASSAGE)
68
Q

What When should you return after injection and what should you do?

A

Return 15 to 30 minutes

Ask if pt feels any acute pain, burning, numbness, or tingling at injection site (possible tissue damage)

Ask pt to discuss implications of skin testing and signs of allergic rxn (ensures they will report timely if bad rxn)

Inspect bleb–read site at 48-72 hours looking for induration (hard, dense, raised area around injection site

easily accessible

muscle is not well developed in many adults

potential for injury because axillary, radial, brachial and ulner nerves and brachial artery lie within upper arm under tris and along humerus

SMALL VOLUME (2mL or less), admin of routine immunizations in toddlers, older children, and adults, other sites inaccessible because of dressings or casts

Patient position: fully expose upper arm and shoulder; ask to relax arm at side or support arm and flex elbow. Do not roll up any tight-fitting sleeve; allow pt to stand, sit, or lie down

Palpate lower edge of acromion process–forms the base of a triangle in line with midpoint of lateral aspect of upper arm–injection site is in center of triangle–3-5cm (1-2 inches) below acromion process. 4 fingers, top one along acromion process–site is three finger widths below
